Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Power Steering Fluid

Check the power steering fluid reservoir for level and condition.
If low or contaminated, drain the old fluid from the reservoir and lines.
Refill with new power steering fluid as per manufacturer specifications.

3. Inspect and Replace Worn Suspension Components

Using a socket set, remove the wheel to access suspension components.
Inspect control arms, bushings, and struts for signs of wear.
Replace any damaged or worn components with OEM or quality aftermarket parts.

4. Examine and Replace CV Joints if Necessary

Inspect CV joints for any tears in the boot or excessive play.
If damaged, remove the axle from the wheel hub and replace the CV joint or axle as necessary.
Ensure proper torque specifications are followed during reinstallation.

5. Check and Replace Wheel Bearings

Lift the vehicle and remove the wheel.
Inspect the wheel bearing for play by shaking the wheel at 12 o'clock and 6 o'clock positions.
If excessive play is found, remove the hub assembly and replace the wheel bearing.
Use a torque wrench to ensure proper reassembly torque.
